Abstract: Well cementing compositions comprise water, an inorganic cement and flexible particles having an average density higher than 1.5 g/cm3. The flexible particles may be elastomers. The flexible particles and cement particles may be present in a trimodal particle size distribution. The compositions may be placed in subterranean wells in the context of primary or remedial cementing.

Abstract: A cement for use in wells in which hydrogen sulfide is present, comprises elastomer particles. In the event of cement-matrix failure, or bonding failure between the cement/casing interface or the cement/borehole-wall interface, the elastomer particles swell when contacted by hydrogen sulfide. The swelling seals voids in the cement matrix, or along the bonding interfaces, thereby restoring zonal isolation.

Abstract: Adding shapeable particles to drilling fluids may be useful for curing lost circulation. When the shapeable particles are pumped downhole through the drillpipe and the drillbit, they may deform when exposed to shear as they pass through the drillbit nozzles. While circulating back toward the surface they may relax at least partially and assume the shape of cracks or voids they encounter along the formation wall, thereby stopping losses.

Abstract: A cement for use in wells in which carbon dioxide is injected, stored or extracted, comprises elastomer particles. In the event of cement-matrix failure, or bonding failure between the cement/casing interface or the cement/borehole-wall interface, the elastomer particles swell when contacted by carbon dioxide. The swelling seals voids in the cement matrix, or along the bonding interfaces, thereby restoring zonal isolation.
